unity3d - 当玩家射击时，它正在失去生命

Question

我正在制作多人游戏 2d，当我的玩家射击时（枪也有对撞机），这会影响他的生活，我不知道为什么。可能是因为当目标“受伤”时有 RPCtarget.all 但我不知道改变什么只是为了影响游戏中的其他玩家，而不是我的。我可以用什么来代替一切？

我认为在这种情况下你并不真的需要 RPC。

我看到你的角色 IPunObservable 并且，我猜，添加到 PhotonView。所以它的健康会自动同步。您还可以使用 PhotonNetwork 实例化子弹，这意味着它们也将同步并具有 PhotonView。

所以每个玩家都有所有同步的子弹和其他玩家。

这意味着，您只需要检查子弹是否来自其他玩家并在本地设置伤害（不用担心，结果会同步），如下所示：

. . .
    private void OnTriggerEnter2D(Collider2D col)
    {
        if (col.gameObject.CompareTag("Hurt"))
        {
            // if hurt object is not mine, take damage
            if (!col.gameObject.GetPhotonView().isMine) 
                Damage();
        }
        if (col.gameObject.tag == "PowerUp")
        {
            if (photonView.IsMine)
            {
                var powerup = col.GetComponent<PowerUp>();
                powerup.Pickup(this);
            }
            else
            {

            }

        }
        if (col.gameObject.CompareTag("Bullet"))
        {
            // if bullet is not mine, take damage
            if (!col.gameObject.GetPhotonView().isMine)
                Damage();
        }
        else
        {

        }
    }

    // no rpc
    void Damage()
    {
        if (!photonView.IsMine) // only player can change his life
            return;

        if (Health > 0)
        {
            Health -= 20;
        }
        if (Health <= 0) // check health status
        {
            myCounts.RpcRespawn(); //Here you should to call counter
            photonView.transform.position = Vector2.zero;
            Health = 100;
        }

    }
